Product details
Overview
71V416L15PHGI8 from Renesas Electronics is a 4 Mbit (256K × 16) low-power, high-speed CMOS static RAM with 15 ns access time, single 3.3 V supply operation, and industrial temperature range (–40°C to +85°C). It features separate byte enable (BHE/BLE), LVTTL-compatible I/Os, and JEDEC-standard center power/ground pinout for noise reduction - deployed in embedded control, industrial PLCs, and legacy telecom interface buffers.
For engineers reviewing the 71V416L15PHGI8 datasheet, 71V416L15PHGI8 pinout, 71V416L15PHGI8 application, or 71V416L15PHGI8 equivalent, key selection criteria include its 15 ns read cycle time, low standby current (40 mA max at industrial temp), TSOP-II package compatibility, and byte-selectable write capability without external logic.
Technical Context
The 71V416L15PHGI8 uses fully static asynchronous circuitry-no clocks or refresh required-and integrates independent high- and low-byte write enable paths via BHE and BLE inputs. Its address decoding supports full 18-bit addressing (A0–A17) for 256K-word access, with all timing parameters specified across industrial temperature and 3.0–3.6 V supply range.
Operation relies on three control hierarchies: chip select (CS) enables memory access, output enable (OE) gates data output drivers independently of write state, and write enable (WE) combined with byte enables determines write granularity (word, high-byte, or low-byte). All I/Os are bidirectional and LVTTL-compatible with defined VOH/VOL under 8 mA sink/source.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4,194,304 bits (256K × 16), enabling direct 16-bit bus interfacing without multiplexing |
| Access Time (tAA) | 15 ns max at –40°C to +85°C, defining minimum address-to-data-valid delay in read cycles |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3 V logic rails and tolerant of ±10% regulation variation |
| Standby Current (ISB) | 40 mA max (industrial grade), enabling low-power hold mode during processor sleep or idle states |
| Byte Enable Inputs | BHE and BLE support independent 8-bit writes - eliminates need for external byte-mask logic in 16-bit systems |
| Output Enable Propagation | tOE = 7 ns max - allows fast turn-on/off of data bus drivers for shared-bus arbitration |
| Package | 44-pin TSOP Type II (PHG44), 400-mil width - surface-mount compatible with standard PCB reflow profiles |
Pinout & Package
71V416L15PHGI8 is housed in a 44-pin, 400-mil TSOP Type II (PHG44) package with JEDEC-standard center power/ground pinout for reduced simultaneous switching noise. Pin numbering follows standard top-view orientation with A0–A17, I/O0–I/O15, and dedicated control signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word decode; no internal latching - requires stable address during CS low |
| CS | Chip Select | Active-low global enable; device enters high-Z standby when high, minimizing bus contention |
| OE | Output Enable | Active-low control for output drivers only; allows read operations while WE remains high |
| WE | Write Enable | Active-low signal initiating write cycles; timing-critical for tWP (10 ns min) and tDW (7 ns min) |
| BHE / BLE | Byte Enable Inputs | Active-low controls for upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes - enables partial-word writes |
| I/O0–I/O15 | Bidirectional Data Bus | LVTTL-compatible 16-bit I/O port; direction controlled by WE state and CS/OE combination per truth table |
| VDD | Power Supply | 3.3 V core supply; two pins (pins 12 and 33) reduce IR drop and improve decoupling effectiveness |
| VSS | Ground | Ground reference; two pins (pins 11 and 34) provide low-inductance return path for I/O and core currents |
Key Features
| Feature | Design Value |
|---|---|
| Low-Power Standby Mode | ISB1 = 10 µA max (static), enabling energy-efficient retention in battery-backed or intermittent-operation systems |
| JEDEC Center Power/Ground | Pins 11 (VSS), 12 (VDD), 33 (VDD), 34 (VSS) placed centrally - suppresses ground bounce and improves signal integrity |
| Asynchronous Operation | No clock, no refresh, no wait states - simplifies timing design in microcontroller- or FPGA-based memory interfaces |
| Industrial Temperature Range | –40°C to +85°C operation validated across full voltage (3.0–3.6 V) and timing specs - suitable for harsh-environment control |
| LVTTL-Compatible I/O | VIH = 2.0 V min, VOL = 0.4 V max @ 8 mA - ensures interoperability with 3.3 V microprocessors and FPGAs without level shifters |

FAQ
What is the maximum operating temperature range for the 71V416L15PHGI8?
The 71V416L15PHGI8 is rated for industrial temperature operation from –40°C to +85°C. This range is fully validated across all AC and DC specifications including access time (15 ns), standby current (40 mA max), and input/output voltage thresholds - ensuring reliable performance in factory automation, transportation, and outdoor equipment applications.
Does the 71V416L15PHGI8 require a refresh circuit or clock signal?
No, the 71V416L15PHGI8 is a fully static asynchronous SRAM and requires neither a clock nor periodic refresh. Its internal CMOS latch-based memory cells retain data indefinitely as long as VDD is applied and CS is held high during standby - simplifying system design and eliminating refresh-related timing constraints in MCU or FPGA memory controllers.
Can the 71V416L15PHGI8 be used with a 5 V microcontroller interface?
No - the 71V416L15PHGI8 is strictly a 3.3 V LVTTL device with VIH minimum of 2.0 V and absolute max input voltage of VDD + 0.5 V (≤4.1 V). Direct connection to 5 V logic violates absolute maximum ratings and risks permanent damage. Level translation (e.g., TXB0108 or discrete MOSFET buffers) is mandatory for 5 V host interfaces.
What is the function of the BHE and BLE pins on the 71V416L15PHGI8?
BHE (Byte High Enable) and BLE (Byte Low Enable) are active-low inputs that independently gate write operations to the upper (I/O8–I/O15) and lower (I/O0–I/O7) data bytes. When both are low, a full 16-bit word write occurs; when only one is low, only that byte is written - enabling efficient partial updates without software masking or external logic.
Is the 71V416L15PHGI8 RoHS-compliant and halogen-free?
Yes - the 71V416L15PHGI8 is a green-part variant (denoted by the "G" in the orderable code) and complies with RoHS Directive 2011/65/EU and JEDEC JS709D halogen-free standards. Lead-free matte tin terminations and bromine-free molding compound are confirmed in Renesas' official material declarations for this part number.
